Embodiment Construction

[0048] In order to enable those skilled in the art to better understand the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but this is not intended to limit the present invention.

[0049] A kind of control method of embedded controller 1 of the embodiment of the present invention, embedded controller 1 (EC, EmbeddedController) is the core component of electronic equipment such as notebook computer, for example, the embedded controller 1 in notebook computer bears the responsibility of notebook computer. Tasks such as built-in keyboard, touchpad, intelligent charge and discharge management of notebook batteries or temperature monitoring. The embedded controller 1 itself also has a memory with a certain capacity to store relevant data, and the application program can write data to it, so as to realize corresponding functions. This method is also applied in electronic devices such as note...

Abstract

The invention discloses a control method for an embedded controller and electronic equipment. The method is applied to the electronic equipment. The method comprises the following steps: presetting aflag bit of the embedded controller; detecting the flag bit when data is written into the embedded controller, and performing a corresponding data writing operation on the embedded controller when theflag bit is a first numerical value; and changing the numerical value of the flag bit so as to prohibit to perform data writing on the embedded controller. According to the method, the condition thatthe embedded controller can be subjected to the writing operation by multiple operators (such as multiple application programs) simultaneously can be avoided, particularly the embedded controller canbe prevented from being illegally operated by a rogue program or equipment and the like, and the phenomenon that an error of the embedded controller occurs due to data conflict or hostile attack andthe like can be avoided.

Description

technical field [0001] The invention relates to the field of intelligent equipment control, in particular to a control method of an embedded controller and electronic equipment. Background technique [0002] Computers and other electronic devices have embedded controllers (EC), which are very powerful, and input terminals such as clients can write data to them to achieve corresponding functions. For example, BIOS or various types of Applications write to it. However, if multiple clients or multiple other inputs do not control when writing data to the embedded controller, it will cause errors, such as writing to the embedded controller within the same time period, which is very likely to cause Data conflicts, resulting in data reading errors, etc., will cause computer and other electronic equipment to crash, restart, or have abnormal temperature, causing damage to computers and other electronic equipment. Contents of the invention [0003] The purpose of the embodiments o...
